地质导向钻井技术在春光油田车排子地区的应用

针对准噶尔盆地春光油田车排子地区的油藏特点,准确分析了该地区的施工难点,根据LWD井眼轨迹控制机理,2007年首次部署了8口水平井,并第1次利用带有双地质参数的地质导向钻井技术控制井眼轨迹,实现了井眼轨迹准确着陆和在油层中有效穿行的目的。通过8口水平井地质导向钻井技术实践,探索了一套利用地质导向技术控制井眼轨迹、寻找油层的开发模式,为后续油藏开发和钻井施工指明了方向。

移动社交网络中即时推荐好友的方法(英)

Differently from the general online social network(OSN),locationbased mobile social network(LMSN),which seamlessly integrates mobile computing and social computing technologies,has unique characteristics of temporal,spatial and social correlation.Recommending friends instantly based on current location of users in the real world has become increasingly popular in LMSN.However,the existing friend recommendation methods based on topological structures of a social network or non-topological information such as similar user profiles cannot well address the instant making friends in the real world.In this article,we analyze users' check-in behavior in a real LMSN site named Gowalla.According to this analysis,we present an approach of recommending friends instantly for LMSN users by considering the real-time physical location proximity,offline behavior similarity and friendship network information in the virtual community simultaneously.This approach effectively bridges the gap between the offline behavior of users in the real world and online friendship network information in the virtual community.Finally,we use the real user check-in dataset of Gowalla to verify the effectiveness of our approach.     

埕岛油田水平井固井水泥浆体系及施工技术

针对胜利海上埕岛油田水平井钻井以及保护油气层的需要,优选了零自由水、低失水、高分散、短过渡、无缓凝、直角稠化固井水泥浆体系,选用了与该水泥浆体系以及海水钻井液体系相容性好的冲洗隔离液,应用了性能优良的固井工具及附件,采取了相应的固井技术措施,已在海上18口水平井的固井施工中取得了良好的效果。
